Are the natural numbers fixed or do they evolve?
In the context of classical mathematik, they don't "evolve".
Hint: The set of all natural numbers, IN, does not change.
So all natural numbers are fixed. Then for every point on the ordinal
line it is determined whether there is a natural number. Although we
cannot determine it because most are dark.
There are no points without numbers.
